We have problems with creating index.
Create Index command with “defer_build” timed out, but Index still appears in Index UI section with status Created and progress at 0%. Trying to start Build or Drop the index returns Index not found response, while other attempts to Create Index results in “Index already exists”.

We have the same problems. The only workaround we found was removing the node from the cluster, then readding it and recreating all indexes from scratch. Needless to say this is not acceptable with big databases. At the moment our database contains 20 million documents and creating indexes takes several days.

this typically happen when someone else grabs the ports indexer needs on the machines. do you have any of the following ports occupied by another process or a virus scanner that may be preventing indexer from grabbing them on the nodes? -adminPort=9100 -scanPort=9101 -httpPort=9102 -streamInitPort=9103 -streamCatchupPort=9104 -streamMaintPort=9105
